380 Functions and commands
two arguments, but only for those roots lying in the rectangle
with sides parallel to the axis having complex a and complex
b as opposite vertices
complexroot(Poly(P),Real(l),[Cplx(a)],[Cplx(b
)])
Example:
complexroot(x^5-2*x^4+x^3+i,0.1)
gives
[[[(-21-
12*i)/32,(-18-9*i)/32],1],[[(6-15*i)/16,(-6-
21*i)/(16-16*i)],1],[[(27+18*i)/
(16+16*i),(24-3*i)/16],1],[[(6+27*i)/
(16+16*i),(9+6*i)/8],1],[[(-15+6*i)/
(16+16*i),(-3+12*i)/16],1]]
cone Draws a cone with vertex at A, direction given by v, half angle
t, and, if provided, height h and –h.
cone(Pnt(A),Vect(v),Real(t),[Real(h)])
conic Defines a conic from an expression and draws it. Without a
second argument, x and y are taken as the default variable.
conic(Expr,[LstVar])
Example:
conic(x^2+y^2-81)
draws a circle with center at (0,0)
and radius of 9
contains If the list or set l contains the element e, returns 1+ the index
of the first occurrence of e in l. If the list or set l does not
contain e, returns 0.
contains((Lst(l) or Set(l)),Elem(e))
Example:
contains(%{0,1,2,3%},2)
gives
3
CONTINUE Used in programming to bypass remaining statements in the
current iteration and begin the next iteration in a loop.
CONVERT Returns the value of an expression subjected to a command.
convert(Expr,Cmd)
Example:
convert(20_m, 1_ft)
returns
65.6167979003_ft
